I Confessed What Happened with My Brother’s Girlfriend

I’m going to tell you something about my younger brother, and I’m not doing it to judge him, because the truth is I’m just as much of a slut as he is. We grew up in a house where sex was never a forbidden topic, and I suppose that’s why the two of us ended up the way we are. I’m two years older than him, so as a kid I got to watch him turn into a man, and as an adult I got to hear things no brother should ever tell his sister.

Lucas’s sex life was always intense. From the moment he started university, he never stopped. His first serious girlfriend, whom I’ll call Vale, practically lived in his room. I’d come home from school and hear them through the wall, not even trying to hide it, as if the house belonged to them. At first it made me a little shy; then I stopped caring. You get used to it, and I’ll admit it, you even end up paying attention.

His real initiation, though, wasn’t with Vale. It was with the daughter of the woman our father was dating at the time. I’ll call her Ana. One night she stayed over at our house, Dad sorted everything out with her mother, and I had just moved in with my first boyfriend, a week before turning eighteen. That same night, Lucas stopped being a virgin with her. He told me later, with that puppyish pride that never left him.

The detail that changed everything in my head I discovered almost by accident. One day, while tidying the bathroom, I found a pair of my used panties where they shouldn’t have been, outside the laundry basket, hidden behind a towel. It took me a while to understand it, and when I did, I didn’t know whether to laugh or cover my face. My brother liked to smell them. Not mine for any special reason, just whichever ones he had at hand.

Over the years that taste turned into a full ritual. His girlfriend back then, Romina, far from being freaked out, played along like no one else could. She would get him other women’s underwear, thongs she would take from other women’s clothes, sometimes from her own cousins, an aunt, sisters-in-law. She didn’t just hand them over: she brought them herself to his nose while they were in bed, feeding that obsession with a patience that, when I found out, left me breathless.

And I found out because he told me. One night he came home half drunk and pretty upset after a party. He sat on the edge of my bed to vent, said things were weird with Romina and he didn’t know whether to keep going. Practical as always, I brushed it off: he was young, he was handsome, he’d have women coming out of his ears. But he shook his head and said the truth.

—It’s not that easy to leave her —he said, staring at his hands—. She makes me feel things nobody’s ever made me feel.

That’s when I decided to really listen. To keep him opening up, I had to open up too, and I told him about my own experiences, about nights with my friend Belén, about what two women can do to each other when no one’s watching. It worked. Lucas let his guard down and started telling me about the intimacy he had with Romina, my sister-in-law, that woman who from the very first day had sparked in me a curiosity I couldn’t quite admit.

What he described to me was a twisted game and, I’ll confess, brilliant. In the middle of sex, with him inside her, Romina would pull some nearby hidden intimate garment out from somewhere. She’d bring it slowly to her face, and just seeing it appear would already drive him crazy. They’d pass it back and forth between them, smell it, kiss through the garment, their tongues meeting through the fabric.

What truly finished him off came at the end. Just before he came, Romina would whisper in his ear whose garment it was. And almost always it was someone from the family, someone close, someone he knew and saw at Sunday lunches. That instant, the one when he found out, was what made him blow. He told me in a detail he didn’t need to give me, and I listened with my breathing getting shorter and shorter.

—And sometimes —he added, almost in a whisper— she’d wrap it around my cock and I’d cum with it on.

I wasn’t prepared for that sentence. I got hot in a way that made me ashamed. You shouldn’t be feeling this, not with him, not because of this. But I felt it anyway, and I felt something else too: the certainty that somewhere in one of those fantasies I was in there, and that Romina was bisexual, I had sensed it all along.

Years passed. They got back together, split up, got back together again, until it ended all at once. Romina found him with another woman in the same house they shared. A stupid, shameless betrayal, in their own bed. And it was right around that time, with the relationship dying by the minute, when what I never told anyone happened.

Lucas was away on a trip, down south. Romina showed up at the house one afternoon, wrecked, sensing what she already knew. I saw how broken she was and didn’t want to leave her alone. We cooked something, put on a series, and I suggested we finish it in my room, more comfortably, away from the living room. I told myself I was doing it to comfort her. The truth is I had spent years imagining that exact situation.

We lay side by side, dressed, watching the screen. At some point I felt her arm slowly cross over my stomach, shy, like she was testing the waters. I didn’t move it away. The night went on, dawn fell, and it was around three when I realized she had fallen asleep pressed against me, her hand still on my stomach.

I turned off the television and left only the little lamp in the corner on. I was about to fall asleep when her hand moved, just slightly, but with intention. I knew right away what she was after. I turned toward her, held her, arranged my face a breath away from hers.

—You’re very beautiful —I told her.

—Thank you, Caro —she answered.

And she said nothing else. She found my mouth and kissed me with an urgency I hadn’t expected, a long, wet kiss, the kind that wipes out any excuse. I felt her tongue pushing its way in, her hand sliding up from my stomach to the back of my neck, and any idea of stopping dissolved right there.

We started slowly, kissing each other’s necks, behind the ear, in that place where perfume mixes with the real smell of skin. And Romina smelled like an aroused woman, like something beyond any fragrance, a warm scent that got into my head and lit me up completely. We spent a good while like that, unhurried, until I couldn’t stand the curiosity anymore and broke the silence.

—What do you like about my brother? —I asked against her mouth.

—That he’s big —she answered, her voice broken by her breathing—. And that he never gets tired.

I laughed softly and kissed her again, and thinking about him, about what those two did, about how many times I’d heard them from the other side of the wall, heated me up in a way that’s hard to explain. I took off her T-shirt. She had medium-sized breasts, round, with pink nipples and pale areolas drawn with a precision that made me want to bite them. And I did bite them, slowly, while she arched her back.

We undressed without haste and without shame. She was fuller than I was, with soft curves; I was thinner, firmer. We touched first with our hands, getting to know each other, and we spoke very little because we both knew why we were there. My fingers found her soaking cunt and hers found mine, and we masturbated at the same time, forehead to forehead, watching each other do it.

Then she turned over and we arranged ourselves one on top of the other, her mouth on my pussy and mine on hers. While I licked her I couldn’t stop thinking that this was the same body my brother was eating, the same legs I’d heard opening so many nights on the other side of the wall. Imagining it hit me all at once, and I felt the way she responded with her tongue, slow and precise, drinking in everything I couldn’t hold inside.

We ended up wrapped in each other’s arms, sweaty, without saying a word, and we fell asleep like that, tangled together, as if none of it needed explaining.

***

Lucas never found out. He’d only know if he ever read this someday. A couple of months later the relationship with Romina ended for good, and with it all the fantasies I had built in my head collapsed, one by one. I had even imagined ways the three of us could end up in the same bed, him, her, and me, and suddenly there was no her anymore.

But he remained. And so did my suspicions. Now, older, putting together the pieces of that season he spent down south after the breakup, I’m almost certain my brother slept with one of our aunts, an old maid who lives there and who always had a reputation for being hotter than anyone. He spent weeks at her house, just the two of them, and I know Lucas too well to believe nothing happened.

My next goal is to get that confession out of him. I want him to tell me with every detail, like he always does. And if it turns out to be true, if he really did fuck our aunt, I’ve already made up my mind: the next person to go through my brother’s bed will be me.
